\ Application filed November 8, 1886. Serial No,2l8,312. (No'mcdel) Toall whom it may concern: The sheets are united in the manner shown Be itknown that I, CHARLES B. NIEHAUS, in Fig. 2. At one side, that havingthe flange of St. Louis, Missouri, have made a new and a, the sheet Arests, at the side of the ceiling useful Improvement in Sheet-Metal orPaper D, Fig. 1, upon a suitable support, such as the 5 5 Ceilings andValls, of which the following is a molding E. At its opposite side thesheet is full, clear, and exact description. upheld by reason of itsflange a being inter- The improvement consists in a special mode lockedwith the flange a of the next sheet, A, ofshaping and uniting theshcetsattheir edges, Fig. 2, the flange a resting upon the flange a,substantially as hereinafter described and and at the same timeconcealing the fastening 6o 10 claimed, reference being had to theannexed I F, used to secure the sheet A directly to the drawings, makingpart of this specification, joist G.

Sheets having been combined in various The sheets A, constructedandunited as de- 85 ways in ceilings and walls, no claim is madescribed, can be used upon a wall or other upi generally thereto, butonly to the special form right construction as well as upon a ceiling;but imparted to the sheet and the special mode of when thus used Ipreferably employ a much uniting the edges of adjoining sheets, asfolflatter bar or piece than the crossbar B at the lows: At one of itsside edges the sheet is joints between the ends of the sheets.

At its oppositeadvantage in combination with the bar 13- side edge the sheet is turnedbackward to form that is, in ceilings having long panels in which thehorizontal or substantially horizontal two or more sheets are requiredto complete flange a, and within the last-named flange the the panel,the sheets may be united midway 95 sheet is shaped to form thelongitudinal bar in the panel by means of the bar B,which, as

This mode of unitingthe 100 about, backward above the depression in the sheets is useful,irrespective of the use of the sheet occasioned by the formation of thebar 0. bars B at the ends of the panels.

The sheets A can be of any suitable metaliron, brass, or copper, forinstanceand they can be formed, also, of paper or pasteboard, and,within the lines of the panel, they can be pressed, stamped, orembossed, to present to the view any desirable ornamental figure ordesign. The sheets A, at their interlocking edges, may also be shaped toform the flanges a" and a, which are useful instifl'euing theconstruction, and also as a means for straightening the sheets at thepoints where the flanges a and a, respectively, bear against theabutting sheet, for sheet metal sheets as they are supplied to the tradeare liable to be more or less untrue at their edges; but suchirregularity can be disposed of in the folds a a.

I claim-- 1. The herein-described ceiling or wall sheet A, having at oneside edge the flange a and at the opposite side edge the flange a, andwithin the last-named flange having the rib C, said flange a beinginclined downward and inward, and said flange a being turned backwardabox e the depression in said rib.

2. The combination of the sheet A, having the flanges a and a and therib G, the sheet A, having similar flanges and rib, and the joist G,substantially as described.

3. A sheet-metal or paper ceiling or wall composed of the sheets A andthe ribs B, said sheets A each at one side edge having a downwardly andinwardlyturned flange, a, and at the opposite side edge having theflange a,

turned backward above the rib O, substantially as described.

4. A sheet-metal or paper ceiling whose sheets A are similarly providedwith the flanges a and e, constructed, respectively, as described, oneof the sheets at the edge having the flange a being secured to the frameof the ceiling or wall, and the flange a of the adjoining sheet beinghung upon the flange a of the first-named sheet, substantially asdescribed.

5. A sheet-metal or paper ceiling whose sheets A are similarly providedwith the flanges a and a, constructed substantially as described, one ofthe sheets at the edge having the flange a being secured to the frame ofthe ceiling or wall, and the flange aot' the adjoining sheet being hungupon the flange a of the firstnamed sheet, and the sheets at their endsbeing connected by means of the bar B, substantiall y as described.

6. The combination, in a sheet-metal or paper ceiling, of the sheets A Aand the folded bar B, substantially as described.

7. The combination of the sheets A A, the cross-bar B, and the cross-barB, said sheets having the interlocking flanges a a, and said bars B Bbeing connected with the sheets, as described.
